2. SQL for Data Preparation

Overview

In this chapter, you will learn how to clean and prepare data for analysis using SQL techniques. We will begin by first learning to combine multiple tables and queries together into a dataset using joins, unions, subqueries, and functions to transform data before moving on to more advanced material. By the end of this chapter, you will be able to transform and clean data using SQL functions and remove duplicate data using the DISTINCT and DISTINCT ON commands.
